1 Claim. (Cl. 229-23) This invention relates to a reinforced carrier receptacle which is economically constructed largely of paperboard stock. Two rectangular sections of paperboard are used with a minimum of waste material, and assembled with a metal internal frame with which said sections of paperboard stock are securely interlocked, providing a receptacle having a bottom of double thickness, vertical sides and ends and an open top, the upper edge portions of the sides and ends being strengthened by inwardly and downwardly turned narrow sections of the paperboard material within the sides and ends, immediately connecting with the sides and ends of the metal reinforcing frame. The ends have hand holes located immediately below said downwardly and inwardly turned portions, the lower edges of which provide surface areas for the hands to engage against so that the receptacle, heavily loaded, may be readily and easily carriedwithout cutting into the palms of the hands of the workmen carrying them. Such carrier receptacle is particularly useful in the handling of bottled beverages which, held in the receptacles and placed upon trucks may be transported from the place where the beverage is bottled to where it is sold.

It is a primary object and purpose of the present invention to provide a receptacle of the type described which is economical to produce, is of great strength and durability, light in weight and particularly effective for the use to which it is designed to be put.

An understanding of the invention may be had from the following description taken in connection with the accompanying drawing, in which,

Fig. 1 is a plan view of a blank of one of the two sheets of paperboard material used in each receptacle.

Fig. 2 is a similar view of the other or second sheet of the paperboard or material used.

Fig. 3 is a perspective View of the preferred metal reinforcing frame.

Fig. 4 is a plan view of the initial step of assembly of the paperboard sheet of material shown in Fig. 2 with the reinforcing frame.

Fig. 5 is a subsequent step of the assembly in which the paperboard sheet of Fig. 1 is assembled with the previously assembled frame and the first sheet of material shown in Fig. 2.

Fig. 6 is a perspective view of the completely assembled receptacle.

Figs. 7 and 8 are fragmentary, somewhat enlarged, vertical sections, substantially on the planes of lines 7-7 and 88 of Fig. 5, respectively, and

Fig. 9 is a perspective view, similar to Fig. 3, of an alternate slightly modified form of reinforcing frame.

Like reference characters refer to like parts in the different figures of the drawings.

The blank shown in Fig. l is made from an elongated rectangular section of the paperboard material, at its middle portion having a rectangular upper bottom section 1, the ends of which are defined by transverse folding lines 2 between the ends of the bottom member 1 and two end sections 3 which are adapted to be turned upwardly about the lines 2 to provide the ends of the completed receptacle. Each of the end sections 3 has a somewhat elongated opening 4 therethrough for entrance of the fingers and part of the hand of one lifting and carrying the receptacle. Each section 3, a short distance beyond its associated opening 4, has a transverse scored folding line 5 and spaced therefrom outwardly a second parallel scored folding line 6 defining and bounding a relatively narrow rectangular section 7, one at the outer end of each of the end sections 3. Beyond the scored or folding lines 6 are terminal flaps 8, the end portions of which are cut away on diagonal lines as shown in Fig. l.

The other sheet of paperboard material, shown in Fig. 2, and used for the receptacle is also made from a rectangular sheet of paperboard material longer than it is wide which, midway between its ends, has a lower bottom section 9 at each side of which and integrally connected therewith is a side section 10, scored folding lines 11 being at the sideedges of the section 9 so that the sides may be turned to vertical position at right angles to the bottom 9. Beyond each of the side sections 9 are projecting portions with spaced scored folding lines 12 and 13, parallel to each other and parallel to the lines 11, thereby defining somewhat narrow elongated sections 14 between the folding lines 12 and 13, and beyond the lines 13 are terminal flaps 15 which at their ends are also cut away to provide diagonal or inclined end edges.

The under bottom section 9 at each end has a narrow projecting section or flap 16, and each of the side sections 10 at each end has a like projecting flap 17. The flaps 16 are adapted to be folded about scored or folding lines 18, one at each end of the bottom 9 and turned inwardly to lie against the upper sideof said bottom section. The end sections 17 of the sides-1t) are similarly adapted to be turned inwardly to be positioned at right angles to said ends 10, folding about similar lines 18 which align with the folding lines 18 at the ends of the bottom 9. Between adjacent ends of the flaps 16 and 17 notches 19 of the form shown are cut, one at each end of each of the folding lines 11.

The reinforcing frame, in its preferred form shown in Fig. 3, has two rectangular open side frames made preferably from suitable wire rod, each with an upper horizontal side 20 and a lower horizontal side 21 spaced therefrom and two vertical ends 22 between the ends of the upper and lower members 20 and 21 integral therewith, it being understood that, preferably, at the lower side 21 of each frame the ends of a length of rod used to make each frame will be brought together and permanently secured by welding. The two side frames are spaced a distance from each other, and transverse horizontal wire rods 23 extend between the upper corners of the respective frames at their ends having a permanent welded connection thereto. From the middle portion of each of the upper rods 20 and 23 a loop 24 depends. Each of the loops 24 made from a length of wire rod is of a shallow U-shape, the upper ends of each of said loops being connected by welding to the rods 20 and 23.

In Fig. 9 the frame structure is identical with that in Fig. 3 except that the upper rods 20 and 23 of the reinforcing frame, between their ends, are provided with integral downwardly extending U-shaped loops which are bent from the rods as shown at 2401, and in which two of such loops 24a are shown in the upper rods 20 and one only in each of the rods 23.

In the assembly, the frame is placed upon the under bottom section 9 with the rods 21 alongside of and closely adjacent to but within the folding lines 11. Each side 19 is turned upwardly to vertical position folding about the lower side rods 21 of the frame. The end or terminal portions of the blank, each including a section 14 and a connected section 15, are folded substantially at the lines 12 around. the upper rods 20 (Fig. 8) being folded inwardly and downwardly so that the sections 14 extend from such upper rods 20 to the lower sides of the loop 24, theterminal flaps 15 being thence folded upwardly within the adjacent side 10. The flaps 17 of the sides extendoutwardly, as at the right hand end of Fig. 4, when said sides have been thus assembled and securely connected with the upper members 20 and their loops 24 of the inner reinforcing frame.

The receptacle is completed by inserting the blank shown in Fig. 1 over the bottom 9 with the upper bottom section 1 directly thereover, the end flaps 16 of the bottom 9 having previously been turned inwardly through substantially 180 to lie against the adjacent portions of the upper side of the bottom 9 as shown at the right in Fig. 4, and

also in Fig. 7. The flaps 17 at the ends of the sides 10 are folded inwardly as shown at the right in Fig. 4 being short enough at their lower ends that they pass over the upper bottom member 1, after which the ends 3 are turned upwardly about the folding lines 2, and the parts 7 and 8 are thereuponfolded inwardly first about the lines 5 around a double thickness and strength bottom and is strongly.

reinforced by the paperboard material at the upper portions of both of the sides and ends. The fingers and parts of the hands inserted through the openings 4, upon lifting the receptacle, come against the rounded lower edges of V the folded parts 14 and 15 and 7 and 8 (Figs. 7 and 8) protecting the hands against heavy pressure which would occur if only the edges of the thickness of the ends 3 at the openings 4 had to sustain the entire weight of the receptacle and its contents. The parts which are used to make one of the receptacles may be shipped fiat and stacked insofar the paperboard material is concerned and the reinforcing frames may be partially nested to reduce space. Assembly when destination is reached is quickly and expeditiously made without the use of tools, stitching machines or anything else being required, the assembly being immediately accomplished solely by use of the hands.

The invention is defined in the appended claim and is to be considered comprehensive of all forms of structure coming within their scope.

I claim:

A receptacle of semi-rigid paper stock comprising, a rectangular bottom wall, side and end walls integrally connected to the side and end edges of the bottom wall extending upwardly therefrom, an open rectangular frame of wire having sides and ends located within the upper end portions of said sides and ends of the receptacle, each side and end of the frame having a shallow U-shaped wire member connected therewith and extending downwardly between the ends of each of said frame sides and ends, said sides and ends of the receptacle having integral extensions connected therewith, folded downwardly and inwardly over the frame sides and ends, and thence upwardly and outwardly under saidU-shaped members and clamped thereby against the side and end walls of said receptacle.
